诺基亚8610手机上壳体注塑模具设计 摘 要 进入二十一世纪以来，中国塑料工业取得了令世人瞩目的成就，实现了历史性的跨越。蓬勃发展的中国塑料工业，在中国现代化经济建设中发挥着越来越大的作用。手机已成为日益普遍的通讯工具，因此其注塑模具的需求也日益增多，市场前景广泛，而且因为不同手机的外形不同，注塑模具也就有了很大的不同。 本课题是设计诺基亚8610手机上壳注塑模具，通过注塑机注塑成形零件，需要选用注塑机。本产品是批量生产，具有很重要的现实意义。本设计主要应该完成对模具的整个设计过程，包括模具的选材，型腔的机构设计，以及对模具的校核，并介绍模具在国内的发展现状和前景。 关键词：手机前壳；注塑模；模具设计 ABSTRACT Into the 21th, The plastics industry of China has made spectacular achievements in the world,it achieved a historic leap. The great development of plastics industry of China, it is playing an important role in Chinas modernization economic construction increasingly . Phone has became an common means of communication increasingly, so the demand of injection mold is growing,and the vista of market is extensive. Because of phones’ shapes are different , so there have quite different in injection mold. This topic is designed the injection mold of Nokia phone.It has injected forming parts through injection molding machine, so it is need to choose injection molding machine. This product ’s production is mass, it has an very important significance. and should be completed on the main mold of the entire design process, including choosing the material of mold,the design of body cavity and the verification of the mold,introduce the development status and Prospects of mold in China. Keywords：Mobile phone upper cover; Plastic injection mould; Mould design 目 录 摘 要 1 ABSTRACT 1 第一章 引 言 5 1.1 课题的目的、意义及设计任务……………………………………………………..5 1.2 我国塑料模具发展趋势分析……………………………………………………….5 1.3 注射成型原理及工艺……………………………………………………………….7 1.3.1 注射成型原理.………………………………………………………………..7 1.3.2 注射成型工艺过程…………………………………………………………...7 第二章 注塑产品分析……………………………………………………………………....8 2.1 塑件的工艺性分析………………………………………………………………….8 2.2 塑件的结构尺寸及表面质量分析………………………………………………….9 2.2.1 结构分析……………………………………………………………………...9 2.2.2 塑件表面质量分析…………………………………………………………...9 2.3 塑件体积和质量的计算…………………………………………………………...10 2.3.1 计算塑件体积 ……………………………………………………………….10 2.3.2 计算塑件质量 ……………………………………………………………….10 第三章 选择注射机………………………………………………………………………..
